- The present invention relates to window sash comstruction, and one of the primary objects in View is to devise an improved construction which will enable both theupper and lower sashes to be adjusted into any desired vertical position, as well as into various inclined positions in which the sashes occupy positions at various angles projecting inwardly toward the interior of the building.

It is also" sought to provide an improved sash construction in which the different sashes can be variously positionedfor a greater range of adjustability for ventilation, and also brought into the most convenient' positions for window cleaning or washing purposes It is further sought to devise a practical and efficient construction of this improved character which will includeWeather-proofing features, to the end that the slideways or grooves between the'sashesand frames will be maintained in as tight-fitting'relation as possible while not interfering in any way with the proper movement andadjustments of the sashes. I I

It is a still further object'of the invention to "devise improvements of this character which will be adaptable to old or established window constructions, in order that the improved features may be embodied therein without requiring a rebuilding of the entire window frame and sash construction,

With the foregoing general objects in view, the invention will now be described by reference to the accompanying drawings illustrating one form of embodiment of the invention which Ihave found to be simple and practical, after which the improved features and combinations thereof will be set I forthand claimed.

Figure 12 is an enlarged detail plan View "86 7 showing one of the upper corner portions of one of the sashes with'the retaining member illustrated in Figure 11; an I Figure 13 is a detail section showing 'a I modified form of slideway construction, I I '90 Referring now to the drawings in detail, in the improved construction the faces-of the .jambs 15 are suitably grooved or recessed to provide the grooves or channels 16 for mounting suitable metal channel 5 strips 17 having the inturned margins as illustrated in Figure 5, and designed to form the guide or slideways for the slide members 18 which are pivotally attached to the sash members 19 and 20. Eachof the slide mem- 10.

bers 18 is of substantially rectangular form in cross section, and provided with the outturned margins 18 for fitting within and being retained by the inturned'margins of the channel members 17. Each of the side margins of the sash member is suitably rabbeted for receiving the corresponding slide member 18, and for producing, a weathermerit. for retaining engagement with a sash cord26 the end of whichis knotted as indicated at 27 after having been passed through the loop or keeper element 25.

Each 'sash cord 26' is carried over a pulley 28 mounted near oneof the upper corners of the window casing-in the usual manner, as indicated in Figure4.

For pivotally mounting each of the sash members 19 and'20 to the Corresponding slides.18, each of the lower corners of the sash members is provided with a suitable bracket member 30 attachedby screws 31 or the like to the sash member, and having an inturn'ed portion 32 extending within a recess 33 cut in the corner of thelsash memher, which intur-ned portion carries a pivot screw-or the like'34which is pivotally connected to thelower end of the slide member 18 and secured thereto by means of a nut 35 and lock washerB'G asclearly' illustrated in Figures 8 andl9. lVith the lower corners of each sash frame cutout slightly, as indicated at 37 (Fig. 10), this pivotal construction permits each of the sash members 19 and 20 to be swung inwardly at difierent angles as represented in Figures 4 and 11.

{For retaining the sash members 19 and '20 normally in upright position, or parallel to the corresponding slide members 18," each of the sashes is provided with a suitable latch'element, comprising, in the case of the upper sash 19, a metal strip or plate 38 pivoted at one end, as indicated at 39, to the upper end of its slide member 18, this plate 38 projecting rearward or toward the in te'rior of the building and resting normally within a kerf or groove 40 cut in the upper edge of the sash frame, a similar cut 41 being made in the upper edge ofthe slide 18 t'o ermit the latch to be swung into horizontal'position. In the case of the lower sash j20','the pivot 39 between the latch member or plate 38 is at the outer face of the slide member 18, in which case no out 41 is required in the. slide,=but a similar kerf 40 is made in the sash frame, as shown in Figure '6; At its free end-the latch member 38 is provided with ailaterally and ,trations' set forth .in the drawings.

downwardly projecting sash engaging portion, turned toward the window casing in the case of the latch element 38, as indicated at 42, and turned in the opposite direction as indicated at 42in the caseof thelatch member 38, each of the sash engaging portions having a slightly curved'end portion as illustratedrin Figure 7 for convenience in engaging the same by the thumb or finger for lifting and releasing the latch. Obviously, the sash engaging portions 42 and 42 serve to effect retaining engagement with the faces of the sash members and thereby retain the members 19 and 20 in upright position, or parallel to their slides 18, so long as these latch elements are so engaged.

I also provide means for suitably latching the sash members in different angular or inclined positions, as represented in Figures 11. and 12. This means comprises a pair of links 44 and 45 which are pivotally connected as indicated at 46, the link 44 being provided at its opposite end with a slot 47 for sliding pivotal engagement with a stud 48 carried by a bracket 49 secured to one of the jamb pieces 15 of the window casing. 7 One end of the other link 45 projects a little past its pivot .46, which projection is formed with a T-slot 50'adapted for deg5 tachable engagement with a lug or finger 51, also secured to the jamb piece 15. This sliding connection at the points 48 and 51 permits the links to be detached from inoperative positioln when thelink retaining means 100,

is to be brought into use. The link 45 is provided on its outer side face with the box loops '52 pivotally connected, as indicated at 53, near the opposite ends of said link, these loops 52 being designed to be fitted over the 1 corner portion of one of the sash members 19 or 20; at such times one ofthe sides of the 7 loop 52 is seated within the corresponding kerf 40 or 40, whereby the sash is retained at that angular position to which it may be 1107 swung, either thesingle link 44, or both of said links 44 and 45 when fully extended, being employed, as represented in Figure 11,- according to the angle of the sashes.

In Figure 13 is illustrated a slight modir fication of the jamb and slideway construction to adapt the improvement to old windows, in which the usual parting stop can be simply cut flush with bottoms of the sash grooves and then a groove 50 cut for seating a flange or bead 17 struck-out from each channel strip 17. This produces the desired weather-proofing function with a minimum of cutting of the window casing, r

The function and use of the improvements .125 will bejreadily understood in the light of the foregoing in connection with the illus- The slide and' channel construction, as represented in Figures 5 and 6, permit all necessary vertical movement of the sash members, while obviously maintaining a most ef-. ficient weather-proof construction at both sides of the sash, in addition to which the tight construction is also maintained at the meeting rails between the'sashes, as represented in Figure 3. Moreover, the pivotal construction at the lower corners of the sash memberspermits the sashes to be swung at different angles toward the interior of the building, even to a substantially horizontal position as represented in Figure 4c.

In swinging both sash members into the latter position, it will be noted that the lower sash is first raised into its topmost position, for which purpose the upper lintel 12 is located high enough to give a slightly increased vertical movement tothe lower sash member as shown in Figure 4, that is, to an extent just sufficient to permit the upper or outer sash member 19, when lowered to the position shown in Figure 4, to clear the bottom rail of the lower sash and swing inwardly to the position shown by the dotted lines in said viewg'thereupon, the inner sash may then be again lowered and swung inwardly on top of the upper sash, all as represented by the dotted lines in said view. In either of these positions it is apparent that the cleaning or washingv of the sashes may be much more conveniently and effectively accomplished than in any of the usual forms of window sash construction.

It will also be apparent that a much more effective ventilation can be carried out by means of the improved construction, which permits the sash members to be swung into any desired inclined position, thus enabling the draft to be controlled, as well as preventing the rain from beating into the room to any extent, when the sashes are arranged in more or less inclined position as shown in Figure 11. The adjustments of the positions of the sash members can be both conveniently and quickly accomplished, after one has learned the necessary movements required for bringing the sashes into any desired position.

While I have illustrated and described what I now regard as the preferred form of construction for embodying the proposed improvements, I desire to reserve the right to make all such changes or modifications as may fairly fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A sash and window frame construction comprising jambs provided with slideways having inturned marginal portions, and a sash having pivotal slides operating along said slideways and formed with outturned flanges engaging within said inturned marginal portions, said jambs and slideways having interengagmg grooves and beads providing weather-proof seals between the comprising jambs, a sash member pivotally mounted within said'jambs, a pair of latch links pivotally connected to each other, a pivotal connection between one of said jambs and one of said links, and spaced elements carried by said links for selective retaining engagement with a portion of said sash member for retaining the latter in different angular positions.

3. A sash and window frame construction comprising'jambs, a sash member pivotally mounted within said jambs, a pair of latch links pivotally connected to each other, a pivotal connection between one of said jambs and one of said links, spaced elements carried by said links for selective retaining engagement with a portion of said sash member for retainingthe latter in different angular positions, and means fordetachably suspending said links in folded inoperative position. 7

In witness whereof I hereunto afiix my signature.
